I don’t know if that’s precisely true, but I do know that when someone tells me what their internal experience is, I believe them. When someone tells me they’re gay or lesbian, I believe them. When someone says they’re attracted to people without reference to gender, I believe them. When someone says they’re not interested in sex with anyone, I believe them. And I don’t think it takes a PhD in sex to recognize that each individual is THE ONE AND ONLY EXPERT on that individual’s sexuality. Asexuality is just another variation on human sexuality. We’re all made of the same parts, just organized in different ways. And if somebody says that’s their internal experience, well they’re the only ones who knows that.
